I cant say much about outside of NH, but if you use google maps, your car and a pair of binoculars, you can find some rad stuff. Look for old rock slides. Make sure you and your partners are prepared for a possible avy.

vincent.ive heard slidebrook at Sugarbush is awesome, but you can get lost really easily. you can go with a guide from sugarbush, john eagon. cool guy

I think it's pretty simple to find your way out and everything eventually funnels out onto the access road. It only becomes loads more complicated and difficult when people don't bring backcountry gear (skins, pack, headlamp, water, layer, etc).
